Can the OCTO drive all 96 LED's if I only connect 48 LEDs per plug?

Yes, it can handle 90 LEDs per channel.
So the OCTO can handle 180 and the Farbwerk 360 can handle 360 LEDs.

Is there a way to "daisy-chain"
the FARBWERK and the OCTO, or are they 2 independent devices require
their own Molex and USB headers?

They are independent devices and need their own connections, daisy chaining is not possible.

well, you can use the PSU's daisy chain Molex plug, but individual USB yes.

They use half width USB plugs (since the 9 pin sockets on the motherboard is two USB ports). So you can plug both to a single USB header.

Also be aware that the Farbwerk360 RGBpx ports have some capabilities that the Octo RGBpx ports do not have. The main difference is the Farkwerk360 supports Transparency. This mean that you can stack multiple effects assigned to the same LEDs. With the Octo RGBpx ports, the highest effect in the stack prevails. With the Farbwerk360 you can set a Transparency level which allows effects lower in the stack to "bleed through" the effects above. It's a little hard to explain but this feature opens up a lot of possibilities. Also, the Farbwerk360 allows up to 20 LED effects (they call them LED controllers) across 4 RGBpx ports. The Octo allows up to 6 LED controllers (effects) per RGBpx port. The point is that the RGBpx ports on the Farbwerk360 have different capabilities compared to the RGBpx ports on the Octo, Quadro, etc.

Another thing to be aware of is that you can't synchronize RGBpx ports on different devices. I have 2 Farbwerk360's in my system and very quickly discovered that there is no synchronization between them. They don't talk to each other. The Farbwerk360 does have an Aquabus port on it. The owners manual says that this port is for future use. I have suggested that they use this port to connect 2 Farbwerk360's to each other, with one becoming the master and the other becoming the slave. This would (hopefully) allow them to operate in sync with each other even when Aquasuite is not running. Aquabus is a serial connection with limited bandwidth. I don't think it can handle ARGB data but it could handle timing and control signals between the units. I think it would be a great use of this now unused port.

Is the LED controller size fixed or can it be adjusted for a different number of LEDs?

The controler size can be everything between 1 and 90 LEDs.

Ok, thanks; I'll take another look on how to do that, when I get to the computer.

From the Owner's Manuals for the Farbwerk360 and the Octo:

The length of the bar (corresponding to the number of LEDs assigned) can be changed by moving the right/left edge of the color bar.

Thanks, not sure how I managed to miss that
